Armendariz et al. [1]} introduced the dynamical concept of “k-essence” to explain the fact
of accelerated expansion of universe. This model solve the fine tuning problem of parameters.
Actually, k-essence is developed on the principle of dynamical attractor solution thats why it works
as cosmological constant at the onset of matter domination. The energy and pressure densities of this model are given as
\(\rho =V(\phi )(-X+3X^{2}),~~~~~~~~~p=V(\phi )(-X+X^{2}).\)
